LUBE 1017OB Lubricant for Oil-Based Drilling Fluids | SLB


Lubricant for oil-based drilling fluids

Schlumberger Oilfield Services

LUBE 1017OB lubricant is an oil-soluble additive specifically engineered for use in all invert-emulsion drilling fluids to decrease the coefficient of friction. Decreasing the coefficient of friction reduces torque, drag, and the potential of differential sticking in the wellbore.

LUBE 1017OB lubricant optimizes the performance of oil-based drilling fluids used on ERD wells or wells with complex trajectories that otherwise would be difficult to drill without exceeding the torque and drag limits of the rig. It also is recommended for slimhole applications to increase the effective weight on bit (WOB) and hence ROP.


LUBE 1017OB lubricant should be added at 1% to 3% concentration by volume depending on the severity of the problem. Care should be taken when adding LUBE 1017OB lubricant to invert-emulsion systems with high solids as viscosity can increase. Pilot testing is strongly recommended to determine any effects on the system's rheological properties for all initial applications and subsequent treatments.

LUBE 1017OB lubricant should be added slowly and directly to the mud system, maintaining a small constant stream wherever there is good agitation or through the mixing hopper.
